FRANK SIMONS, OF ST. LOUIS, MISSOURI.

BELL-RINGER.

To all whom it may concern:

Be it known that I, FRANK SIMoNs, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have inventedcertain new and useful Improvements in Bell-Ringers, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to improvements in pressure bell ringers and hasfor its object to provide simple and eflicient means for automaticallystarting and continually ringing any bell to which it may be attached,and is particularly adapted for use upon locomotives, fire engines,ships, and at light houses. The mechanism involved may, also, besuccessfully employed to actuate whistle valves and other similarcontrivances.

Serial No. 519,304.

The piston 3 is provided with ordinary packing rings 8 and with thepassage 9 through which motive fluid is admitted into cylinder 1. Theshoulder 10, which is formed as a peripheral enlargement of said piston,limits the upward movement of cylinder 1. The valve casing 11 is fittedinto the upper end of passage 9 and is provided with the aperture 12,which communicates with said passage and with the interior of dome 4.

The valve 13 is provided with the stem 14:, which is adaptedreciprocatively to operate in aperture 12, and is adapted to engage theseat 15 in said aperture, thereby controlling the admission of motivefluid into the interior of dome 4. The flattened portions 16 and 17 areformed on valve 13 and stem 14:, respectively, and allow the motivefluid to enter dome 4 from passage 9 when said valve is not inengagement with seat 15. The valve 13 normally occupies the positiondepicted in Fig. 3, but, when it is raised by the pressure of the motivefluid, the stem 14 protrudes above the valve casing 11 into the path ofmovement of projection 5 in the interior of dome 4;. The motive fluid isconducted to the passage 9 through pipe 18, which on a locomotive wouldbe connected with the boiler and the admission of the motive fluid intosaid passage would be governed by a valve in the cab of the locomotive(not shown in the drawings).

The bracket 19 is provided with an opening 20 over which rests theshoulder 21 of the piston 3' and under which said piston is fastened tosaid bracket by the nut 21*. The bracket 19 is fastened to the frame 22of the bell 23 by the U-bolt or clamp 24; and the nuts 25, which, whenloosened on said bolt, permit said brackets to be raised or lowered asmay be desired.

The crank 26 is fastened to the gudgeon 27 of bell 23 by the set-screw28. Roller 29 is rotatably mounted on the pin 30, which is fastened inslot 31 in crank 26 by the nut 32 and is capable of adjustment therein,whereby the length of the rock-arm can be lengthened or shortened. Saidcrank 26 is fastened to gudgeon 27 in such position above the roundedtop 4 of cylinder 1 as to cause roller 29 to be disposed in the path ofmovement of said rounded top and to be engaged and raised thereby.

In the alternate form of the piston illustrated in Fig. 6 the cylinder,being substant-ially the same as shown in Fig. 3, is not depicted. Theangle fitting 33 can be advantageously used in some cases, and this isconnected to the piston 3 by the two-way coupling 34, which is providedwith the aperture 35. The valve-seat in this form is located at 36 andis adapted to engage valve 37 when same is raised by the motive fluid tothe position as shown in Fig. 6. The valve-stem 38 is formed with theflat side 39, which allows the motive fluid to pass through aperture 35and into passage 9 when the valve 37 is not in engagement with its seat36. The plunger 40 is adapted reciprocatively to operate in the passage9 and in aperture 12 and is of such diameter as to allow the motivefluid to pass through said passage 9 and said aperture 12 and into dome4. Said plunger rests on the valvestem 38 and, when raised thereby tothe position illustrated in Fig. 6, the upper end of said plungerprojects into the path of movement of projection 5 within dome 4.

In Fig. 7 is depicted an alternate form of bracket 41, which is providedwith the slot 42. A pin 43 having the flattened portions 44 fits in anopening 45 in the bell frame 22 and is secured therein by the pin 46.The flattened portions 44 of pin 43 fit closely to the sides of slot 42and prevent the turning of bracket 41 which is held to said pin 43 bythe nut 47.

The alternate form of exhaust port, illustrated in Figs. .12 and 13,acts as a relief chamber for cylinder 1. In this form the cylinder 1 isprovided with an enlarged portion 48 in which the opening 49 is formedand screw threaded to receive the plug 50. Aperture 51 in said plugterminates at its upper end in aperture 52, which communicates with theatmosphere outside of cylinder 1 and the lower end of said aperture 51is adapted to form the seat 53 for the ball 54. The exhaust passage 55extends from a point near the top of the interior of cylinder 1 to thebottom of opening 49. The projection 5 is omitted entirely and theinterior of cylinder 1 formed as shown in Fig. 13.

The operation of the device is as follows: Steam, compressed air, orother motive fluid is admitted into passage 9 from the source of power,thence expands upwardly through aperture 12 and into the interiorchamber of the rounded top 4 where it exerts its force thereagainstforcing cylinder 1 upwardly on piston 3. This upward movement ofcylinder 1 causes the rounded top 4 to engage roller 29, which ridesthereon and forces the crank 26 to one side or the other, therebyrocking gudgeon 27 and ringing bell 23. When the cylinder 1 has reachedthe limit of its upward stroke, 2'. 6., when nut 6 has been moved toengagement with shoulder 10, the ports 2 occupy a position above the topof piston 3. The motive fluid in the dome 4 being allowed to exhaustthrough ports 2, the supply of motive fluid in the passage 9 ispermitted by the clearance of said dome to rush with added force intothe interior of dome 4 and cause the valve 13 to engage seat 15, wherebythe admission of said motive fluid into said dome is cut off and thestem 14 is forced upwardly into the interior of said dome. The releaseof pressure by the seating of the valve 13 upon the seat 15 of themotive fluid in the interior of the dome 4 allows cylinder 1 to descendunder the pressure of roller 29, which is forced downwardly by the bell23 returning to its normal position. This descent of cylinder 1 causesprojection 5 to engage the end of stem 14 and to push same downwardly,whereby valve 13 is moved from engagement with its seat 15 and motivefluid is again allowed to enter the interior of the rounded top 4. Themomentum acquired by the bell 23 in returning forces roller 29 to rotateto the opposite side of the center of the rounded top 4. Simultaneouslywith the passing of roller 29 to the opposite side of the center of therounded top 4, the motive fluid which has entered the interior of saidrounded top forces cylinder 1 upwardly. Roller 29 again rides on therounded top 4, but on the opposite side thereof, and rotates crank 26and gudgeon 27 in the opposite direction, thereby ringing bell '23.Valve 13 is closed as before, when the cylinder 1 reaches the end of itsupward stroke, and allows the bell 23 to return causing roller 29 toforce cylinder 1 downwardly. Roller 29 is carried over the center of therounded top 4, the valve 13 is reopened, and the cycle is repeated untilthe motive fluid is shut ofl. When motive fluid is admitted intocylinder 1 having the alternate form of exhaust port, the ball 54 isforced against seat 53 and the motive fluid exerts its pressure againstthe interior of the head of said cylinder which is' forced upwardlythereby until it reaches the end of its upward stroke where the pressureof the motive fluid in said cylinder is cut ofl. The ball 54 then dropsfrom engagement with seat 53 and allows the motive fluid in the interiorof said cylinder to exhaust when roller 29 forces said cylinderdownwardly. The motive fluid remaining in the interior of cylinder 1 iscompressed by the downward movement of said cylinder and is forced intopassage 55 from which it exhausts through aperture 51. To facilitatethestarting of the bell automatically, the crank 26 is secured in suchposition to the gudgeon 27 as to cause roller 29 normally to occupy aposition on one side of the center of dome 4, whereby said roller iscaused to ride readily on said dome and said crank forced to one sidethereby, thus obviating j usted relative to roller 29 in order to causedome a normally to occupy a position below said roller but at a distancetherefrom, and, when motive fluid is introduced into dome 4, saidcylinder is set in motion before engaging said roller thereby causingdome 4. to impact said roller which is forced to one side or the other.
